NSImageView 动画

我是Mac开发新手，我们有类似的方法吗imagev = [NSArray 数组WithObjects

我需要像我们在 iOS 中所做的事情想要在 mac 中做的事情，

imageVie.animationImages = [NSArray arrayWithObjects:
 [UIImage imageNamed:@"1.png"],[UIImage imageNamed:@"2.png"],
 [UIImage imageNamed:@"3.png"],[UIImage imageNamed:@"4.png"],
 [UIImage imageNamed:@"5.png"],[UIImage imageNamed:@"6.png"],
 [UIImage imageNamed:@"7.png"] ,nil];

在 iPhone 中，我如何制作动画

Regards

我发现有人使用核心动画解决这个问题的方法 https://stackoverflow.com/q/13011527/449161这对我来说已经足够近了。我稍微修改了一下。你需要@import QuartzCore;

- (void)awakeFromNib
{
    CALayer *layer = [CALayer layer];
    NSMutableArray *spinnerImages = [NSMutableArray arrayWithCapacity:30u];
    for (NSUInteger i = 0; i < 30; ++i)
    {
        NSString *imageName = [NSString stringWithFormat:@"spinner%@", @(i)];
        [spinnerImages addObject:[NSImage imageNamed:imageName]];
    }
    self.spinnerImages = spinnerImages;
    layer.frame = self.imageView.bounds;
    [self.imageView setLayer:layer]; // This view is just a container for the layer. Its frame can be managed by a xib.
    self.imageView.wantsLayer = YES;

    self.spinnerLayer = layer;
}

然后你可以像这样设置动画：

- (void)stopAnimating
{
    if ([self.layer.animationKeys containsObject:kAnimationKey])
    {
        [self.layer removeAnimationForKey:kAnimationKey];
    }
}

- (void)startAnimating
{
    if ([self.layer.animationKeys containsObject:kAnimationKey])
    {
        return;
    }
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:kAnimationKey];
    [animation setCalculationMode:kCAAnimationDiscrete];
    [animation setDuration:1.0f];
    [animation setRepeatCount:HUGE_VALF];
    [animation setValues:self.spinnerImages];
    [self.spinnerLayer addAnimation:animation forKey:kAnimationKey];
}
